Re: fatal:conform: The array to be conformed must have the same number of dimensions as indicated by the length of the last argument

Dear Mary,
Thanks for your response, I have followed your guidance but the problem is
still exist. variable t (temperature; 23 level) has four dimension like:
time: [0.5..143.5]
            lev: [0..1000]
            lat: [90..-90]
            lon: [ 0..358.75]
but the levels started from 0 to 1000
and q (specific humidity;12 level) is also four dimension,but the levels
started from 100 to 1000:
time: [0.5..143.5]
            lev: [100..1000]
            lat: [90..-90]
            lon: [ 0..358.75]
when I calculated w (mixing ration) it gives the followings output:[time |
24] x [lev | 12] x [lat | 145] x [lon | 288]
but when I used the function : rh = relhum (t, w, conform(t,p,1))) for
calculating the RH it gives the following error give below and print
variable summary is also given.
According to my idea the problem is level and I do not know how to make the
equal level of w and t? Please someone give me help to figure out this
problem.
thanks in advance and regards,
